Monster Army

A naked man could be seen taking a bath in a river in the middle of the wilderness.

Tens of thousand of monsters surrounded him but none of them dared to attack him.

They simply stared in the direction of the young man and awaited his next commands.

All of a sudden, they started to move around and charge outward and away from him. 

Nial had given them a mental command using [Dominion].

From the moment he left Alliance City, he had begun to amass a huge army of monsters. 

His mission was to make sure that certain types of monsters would consider him as the leader of their group, pack or horde. 

Not all monsters had a leader or accepted an alliance with other kinds of monsters. Thus, it took Nial a while to get his hands on various monsters at the Prometheus rank and subdue them.

He altered their mind lightly to make sure that it wouldn't be too difficult for him to control an enormous number of monsters.
